ELECTRIC-LIGHT FIXTURE.

Application filed September 18, 1914.

To ZZ whom t may concern:

Be it known that LW'iLLiAM J. BOHAN, a

citizen of the United States, and resident of St. Paul, county ofRamsey, and State of ldinnesota, have invented certain new and usefulImprovements in Electric-Light Fixtures, of which the following is aspecification, and which are illustrated in the accompanying drawings,forming a part thereof.

The invention relates to electric light fixtures, its object being toprovide a fixture which can be employed in exposed situations withoutdanger of loss of any of the parts by pilfering. It is well known thatelectric 'mentioned and also securing a rigid fixture especially adaptedfor use in situations where it is subjected to serious vibration.

ln the accompanying drawings-Figure 1 shows a side elevation, some ofthe parts being broken away, of a table lamp embodying the invention;Fig. 2 is a side elevation, partly in section, of a pendent lamp; andvFig. 3 is a side elevation, partly in section, of a wall lamp.

There is shown in Fig. 1 a base or standard 10, adapted to rest upon atable, and having' a suitable nipple 11 for the insertion of electricwires 12. 'The upper end or stem of the standard 10 is socketed, and thewalls of the socket are provided with an upwardly facing seat, hereshown as formed of a plurality of shoulders 13, 14, this seat beingadapted toreceive and support the base .l5 of anelectric bulb 16 and asa point of attachment therefor, such attachment being convenientlysecured by the use of screws 17. Arms, as 1S, 19, as many in number asmay be desired, extend outwardly and preferably upwardly from the upperend of the stem of the standard, and at their outer ends carry adome-shaped re- 'flector 20. The standard, the shoulders 13,

14, the arms 18, 19, and the reflector 2O are all formed integral.

The constructions illustrated in Figs. 2 and 3 differ from that of Fig.1 only in that they are provided with bases 21, 22, adapted forattachment to a-ceiling or wall, and the reflectors 23, 24, are reversedfrom the position shown inv Fig. 1 and are formed by extending andflaring outwardly the walls of the socketed end of the stems 25, 26, ofthe standards or bases.

The fixture may be made of any suitable material, either metal, plasticor vitreous.

ln order to secure the highest eliiciency of a reiiector it' isimportant that the bulb be located approximately at its focal pointVarious styles of bulbs are made which vary in length, and the lixtureforming the subject of this application readily adapts itself to the useof any of these bulbs, as the shoulders 13, 14, may be made ofsufficient height to accommodate the shortest forms and may be readilycut away to suitably locate the longer forms of bulbs. In Fig. 3 the'shoulders 13, 1&1, are shown as reduced in height for this purpose.

l.' claim as my invention-- 1. An electric fixture comprising a base, areflector, and a socketed stem uniting the base andreiiector, such partsbeing formed integrally, the socket walls being provided with integrallshoulders constituting seats and points of attachment for an electricbulb. i

2. In an electric fixture comprising a shade having a tubular stemprovided with an outwardly facing shoulder forming a` seat and point ofattachinent for an electric bulb, such parts being integral.

3. An electric lamp fixture comprising, in combination, a stem having aseat for a lamp socket, a reflector for a lamp carried by such socket,and arms projecting frointhe stem and carrying the reflector, the stentiarms and reflector bein integral.
